Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for air conditioner installation, and in particular to a fall protection device for outdoor air conditioner units. Background Technology

[0002] With the improvement of people's living standards, the demand for air conditioners is increasing, and they have become an essential appliance in almost every household. They are mainly composed of indoor and outdoor units. In high-rise buildings, the outdoor unit is usually fixed to the outer wall of the cavity by a bracket. In order to improve the safety of installers, trapezoidal fall protection devices are now commonly used for auxiliary installation. The pad at the top of the trapezoidal frame is placed on the windowsill, and then the limiting pins are inserted into several limiting holes on the pad to achieve stability and prevent falls. However, the length of the existing trapezoidal structure is mostly not adjustable, and there is also the problem of discontinuous width adjustment when inserting the pins into the limiting holes. With different wall widths, only similar hole positions can be selected for insertion and limiting, leaving some gaps, which can easily reduce the overall stability. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-3 As shown, the anti-fall protection device for the outdoor unit of the air conditioner mainly consists of a lifting frame 1, an upper ladder column 2, and a lower ladder column 3;

[0021] The bottom sides of the lifting frame 1 are fixedly installed with upper ladder columns 2. The front side of the upper ladder column 2 is provided with an upper column sliding groove. The upper column groove slider 19 is slidably installed in the upper column sliding groove. The top of the lower ladder column 3 is fixedly installed on the outer side of the upper column groove slider 19. The bottom front side of the lower ladder column 3 is provided with a pedal mounting protrusion 17. A pedal 5 is rotatably installed on the pedal mounting protrusion 17. The pedal 5 is used for installers to step on and cushion their feet.

[0022] The front side of the lower ladder column 3 is provided with a lower column slide groove 13. A lower column limiting slider 14 is slidably installed in the lower column slide groove 13. A pedal retraction rod 15 is hinged to the lower column limiting slider 14. The other end of the pedal retraction rod 15 is hinged to the pedal 5 through the pedal hinge 16, so that the pedal 5 can be retracted and put away, making it convenient to carry.

[0023] Limiting and flipping frames 6 are rotatably installed at both ends of the lifting frame 1. The end side of the limiting and flipping frame 6 is fixedly installed together with the window sill pad frame 7 set on the back side of the lifting frame 1. The window sill pad frame 7 is provided with several stop block grooves 23. A stop block 21 is slidably installed in the stop block groove 23. A stop rod 22 is hinged on the stop block 21. In use, the stop rod 22 rotates to make it perpendicular to the window sill pad frame 7, driving the stop block 21 to clamp it to the wall.

[0025] A drive screw 24 is rotatably installed in the stop block groove 23. The stop block 21 is provided with a drive hole. The drive screw 24 is threaded into the drive hole. One end of the drive screw 24 extends to the outside of the window sill pad 7 and is equipped with a knob (not shown) to drive the stop block 21 to move and clamp it in accordance with the wall thickness of the window sill.

[0026] The lifting frame 1 is fixed with flip limit pins 8 at both ends. The limiting flip frame 6 is provided with a slot 9 that matches the flip limit pin 8. When flipping, the slot 9 is locked by the flip limit pin 8 and then padded.

[0027] The bottom of the upper column slide groove is provided with a reinforcing insertion hole, and a reinforcing column 4 is inserted into the reinforcing insertion hole. The bottom end of the reinforcing column 4 extends to the bottom of the upper ladder column 2 and is connected to the lower ladder column 3 through the reinforcing bracket 19.

[0028] Both the upper column slide groove and the lower column slide groove 13 are provided with pin holes 11. A limit pin 10 is installed in the pin hole 11. Here, the pin hole 11 is a threaded pin hole, which is used to lock the upper column slide slider 19 and the lower column limit slider 14.

[0029] A limiting protrusion 25 is connected to the outer side of the blocking slider 21 to limit the flipping angle of the blocking lever 22.

[0030] The lifting frame 1 is provided with a handle hole 10 and a safety ring 26.

[0031] A horizontal ladder frame 12 is installed on both the upper ladder column 2 and the lower ladder column 3.
